Ice area: 134 km2 (51.7 sq miles)
Length: 17 km (10.5 miles)
As with other glaciers, it was Father De Agostini who named this glacier, and he did it after the Italian-Argentinian Botanist and Fungi Investigator.
In 2010, the Spegazzini Glacier was 1.3 km (0.80 miles) wide, 17 km (10.5 miles) long, and had an ice area of ~137 km² (52.8 sq miles). Spegazzini Glacier is another exception to the general retreat of Patagonian glaciers: From 1968 to 2010, the ice front retreated just 150 m (492 feet), with a loss of only 0.07 km² (0.027 sq miles).
In 1986, Spegazzini was almost 1.4 km (0.87 miles) wide, 17 km (10.5 miles) long, and covered an area of 137 km² (52.8 sq miles).
The area of the glacier remained almost the same, being an exception to the general retreat of glaciers. From 1968 to 2008, the decrease of its area was only 0.03 km² (0.011 sq miles).
Spegazzini Glacier has a high calving face, giving origin to icebergs of very different shapes and colors. The glacier is grounded on the bottom of the lake, which depth in this area is around 150 meters (492 feet).
